The ICPSR Summer Program 2005

The ICPSR Summer Program web site containing the 2005 Program information/catalog, and application is up and running.

(information from the Summer Program web site)

The ICPSR Summer Program

Since its inception [in 1962], the Consortium has offered the ICPSR Summer Training Program as a complement to its data services. The Summer Program provides a comprehensive, integrated program of studies in research design, statistics, data analysis, and social science methodology. Its instructional environment stresses integration of methods of quantitative analysis within a broader context of substantive social research. Instruction is grounded in interactive, participatory data-analysis utilizing high-end, networked microcomputers. Because of the range of methodological instruction, the opportunity for intensive study, and the quality of instruction and supporting facilities, the Summer Program has become internationally recognized as a preeminent forum for basic and advanced training in the methodologies and technologies of social science research and instruction.

There are two four-week Summer Program sessions, with intensive seminars, special workshops that provide participants with opportunities to examine the impact of various methodologies on specific substantive issues, and workshops that address the practical objectives of providing technical support for computing specialists and data librarians. In addition, research scholars who have made important contributions to the development of social methodology present informal lectures focusing on their most recent research interests.

Participants in each year's Summer Program generally represent about 25 different departments and disciplines from over 200 colleges, universities, and organizations around the world. While sociology, psychology, and political science continue to be represented by the largest number of participants, the increasing number of individuals from across the social and behavioral sciences illustrates the breadth of interest in and impact of the Program.

The Mission of the Summer Program

ICPSR Revises File Naming System

On January 10, 2005, ICPSR made major changes to the way it identifies data and documentation files. Users who download files should note the following changes:

* All files will include Windows-style suffixes
* Files will have simple text names, rather than acronyms or codes
* Files will include the study number and dataset number (where appropriate) in the file name
* Files will be bundled into study- and dataset-level folders
* File-level information is now recorded in a separate document called the file manifest, instead of within the Readme file.

Our goal is to make the file labels meaningful for our users, and to use a file naming system that does not force users to rename files in order to use them with their preferred statistical packages.

For example, with the old file naming system, if you downloaded datasets 1 and 2 for study 6849, the file names on your desktop looked like this:

|-- cb6849.all6m.pdf
|-- README.6849
|-- da6849.icsbkg
|-- sp6849.ics6m
|-- sa6849.icsbkg
|-- sa6849.ics6m
|-- ug6849.all.pdf
|-- sp6849.icsbkg
|-- da6849.ics6m
+-- cb6849.allbkg.pdf

With the new system, the file names look like this:

+-- ICPSR6849
|-- 06849-manifest.txt
|-- 06849-readme.txt
|-- DS0001_ICS_Background_Data
| |
| |-- 06849-0001-Data.txt
| |
| |-- 06849-0001-Codebook.pdf
| |
| |-- 06849-0001-User_guide.pdf
| |
| |--
| |
| +-- 06849-0001-SPSS_setup.sps
+-- DS0002_ICS_6-Month_Review_Data
|-- 06849-0002-Data.txt
|-- 06849-0002-Codebook.pdf
|-- 06849-0002-User_guide.pdf
+-- 06849-0002-SPSS_setup.sps

As a side note, we are dropping the term "data definition statements" and using the term "setup files," which is more commonly used in the social science community.

For users who make use of our batch downloading function, you may wish to read over our notes on Winzip and "saved files" utility.

ICPSR MyData System

MyData includes a new user registration and authentication system for the ICPSR (Inter-university Consortium for Political and Social Research) Web site. The system will create a more secure environment for users and will also enable them to sign up for notification services that ICPSR is developing. MyData has features similar to many popular Internet Web sites:

ICPSR has updated the "shopping cart" software that works with the new MyData system. Some of the enhancements you can expect as part of MyData include:

When a user begins to download data via MyData, s/he will be prompted either to log in as a returning user or to create a new account. When a user creates a MyData account, s/he will be asked to complete a brief questionnaire about user preferences.

More information about MyData is on the ICPSR Web site.
